Exceptional Value - Save $50 while supplies last. All Sales Final.The Omano OM4424 is the sister microscope to the OM4413, the difference being that the OM4424 has a pole stand. It is a solidly built dual power, stereo microscope designed to withstand the rigors of an industrial setting at an affordable price. It includes dual power, 20x-40x magnification and variable halogen upper and base lighting to make it one of our most popular dual power stereo microscopes.OpticsWith two wide field WF 10x eyepieces and achromatic, coated 2x and 4x objective lenses, the OM 4424 offers 20x/40x dual power magnification. Built more solidly than the OM24L, this stereo microscope has proved endearingly popular over the past ten years owing to a combination of good quality optics, rugged construction and affordable price. It is well-known for its distinctive, double wide base. The head, which is inclined at a 45 degree angle, rotates through 360 degrees for flexible viewing positions. A diopter on the left ocular enables individual eye adjustments while the interpupillary distance adjusts through 50-70mm.Focus & IlluminationSimilar to all our stereo microscopes, the OM4424 includes dual-sided focusing controls so that either hand can be used to focus. Illumination is powered by 110 volt, 12V 10W halogen in both transmitted (bottom) and incident (top) illumination. There are three light settings (top, bottom and top/bottom together), all of which have adjustable intensity. Two spare bulbs are included, one for the top and one for the bottom light.StandThe OM4424 has a pole stand. Pole stands offer greater flexibility than fixed arm stands since they can be used to view specimens off the stage (larger objects for example) while they can also be used in conjunction with a 0.75x or 2.0x auxiliary Barlow lens.We now have an optional hard-sided aluminum microscope case to ensure your microscope investment is always well-protected from the dust, nicks, scratches and dents from everyday use.
